Boyes
Former Pindar House, Scarborough
Roof Cladding, Wall Cladding & Wall Coatings
Boyes asked Roofclad systems to remove all penetrations and vents at roof level as well as strip the existing high level wall and roof cladding. The roof area was split into 11 different areas, 10 of which were to be overclad and 1 of which was to install a new flat roof felt system. Three wall elevations to the rear of the building required stripping and replacing with composite panels whilst the remaining wall elevations were to be resprayed to give the building an improved roadside appeal.
Boyes had recently acquired the former Pindar House building, previously occupied by Pindar Print PLC, on Thornborough Road in Scarborough. The building was in a poor state of repair and in its current condition was not fit for the purpose Boyes required it for. There were leaking and blocked gutters, multiple surplus penetrations in the roof and high level elements to the roof that simply weren’t required along with a multitude of leaks throughout the building.
At Roofclad Systems we supplied and erected a triple handrail scaffold to all exposed roof edges along with scaffold access towers to eaves level complete with fixed ladder access. Due to access issues to one of the wall elevations we installed a fully independent scaffold to allow safe and easy access to the walls, all in accordance with the Working at Height Regulations.
To the raised roof sections of roof areas along with all areas with penetrations we rigged and dismantled plain safe net systems, beneath roof, in accordance with the recommendations of EN1263-2. Access to install these were gained by using a mobile telescopic boom. All connections were knotted around primary truss members, temporary support ropes or other suitable anchorages. The boom formed part of the rescue plan and therefore remained on site for the duration of the roof works.
For the purpose of raising new materials to roof level and lowering redundant materials to ground level we supplied a rough terrain telescopic forklift. All operatives using this equipment had the appropriate training certificates.
For the demolition works to the high level areas we progressively removed the existing roof and wall cladding, leaving the existing steel structure in-situ. We lowered the materials to ground level and cleared away from site. The remaining steelwork was removed and altered by others to allow us to line the exposed area with a bright white liner.
For all of the roofs, excluding the flat roof, we supplied and installed an insulated over-clad system incorporating 80mm glass fibre insulation with a bar and bracket system before 0.7mm thick 32mm deep profiled top sheet. The bar and brackets systems used, had to take into account the different heights and dimensions of the varying profiles of the existing roofs to ensure the top sheets ran through at a consistent height. The sheets were secured using nylon headed stainless-steel fixings and side laps were stitched with stainless steel, self-drilling stitchers. Our in house fabrication team manufactured all internal and external flashings.
The roof works also incorporated approx.. 400lm of trimline gutter replacement and approx. 480lm of Weatherfast gutter lining, along with all new outlets and stop ends. Again, this was all fabricated in house at our head office location in Washington. With works underway it was identified that one of the valley gutters, which incorporated a syphonic drainage system, was failing. This whole gutter line of drainage was replaced with a new syphonic system that was capable of serving the quantity of water the two slopes would direct to the valley gutter.
A small flat roof was stripped back to the deck before we replaced it by priming the roof area and adhering 70m2 PIR 120mm flat roofboard. Self-adhesive VCL and then underlay was put down before a 4mm torch on cap sheet. We boxed off all protruding steel work that once held an abundance of air handling units.
Our operatives stripped over 1000m2 of twin skin wall cladding and replaced with Tata Steel Trisomet 80mm composite panels. All flashings and trims manufactured by Roofclad Systems.
Approximately 2500m2 of vertical wall cladding was pressure washed and recoated using Tikkurila Temadur 20 to give the front elevations a new lease of life and tie in with the newly installed composite wall panels.
Unfortunately due to the location of the building there is a big issue with seagulls in the area. This roof will require regular gutter maintenance to ensure downpipes and outlets don’t become blocked over time.
